Placement OpenStackClient Plugin (Queens)

This blueprint is for creating an openstackclient plugin for the placement service.

The plugin will not live in the nova tree, or python-novaclient. It will live in it's own repo (maybe openstack/placement-osc-plugin).

We can follow Dean Troyer's osc plugin reference here: https://github.com/dtroyer/osc-plugin

The placement REST API version history is here:

https://docs.openstack.org/developer/nova/placement.html#rest-api-version-history

The purpose of the placement osc plugin is simply to provide CLIs for the placement API.

There is no plan to write a python API binding client for placement. The OSC plugin should use keystoneauth1 to find the placement endpoint in the service catalog and make requests, then get the json response data and use that to provide output in whatever form is requested, e.g. a table of existing resource providers or a specific field value for a specific resource provider.

Examples of CLIs we'd like to see are in the original nova spec for generic resource providers:

Here are is the guide for creating new projects in openstack:

This would go under the compute program in governance.
